CVE-2026-12434
List category posts <= 0.95.0 - Missing Authorization to Authenticated (Contributor+) Sensitive Information Exposure via 'post_status' Shortcode Attribute
Description

The List category posts plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 0.95.0 via the sanitize_status. This makes it possible for authenticated attackers, with contributor-level access and above, to extract titles, full content, excerpts, dates, authors, and custom-field metadata of other users' pending-review, scheduled, and trashed posts by embedding a crafted [catlist] shortcode in their own draft and previewing it. This vulnerability is a bypass of the incomplete fix introduced for CVE-2025-11377 in version 0.93.0.
